摘要
在单个供应商和多个零售商构成的易逝品两级供应链中,市场终端价格固定,各个零售商对称且在同一区域市场销售相同产品,市场需求不确定;库存越多,销量期望值越大,零售商之间存在库存竞争。采用贴近实际的有效需求函数证明供应商采用回购合同时,零售商库存竞争存在惟一的纯策略纳什均衡;同时回购合同可以实现供应链协调,能在供应商和零售商之间任意分配整个供应链期望利润;最后讨论回购合同常见的几个原因。
In a two-echelon supply chain of perishable goods consisted by a supplier and multi-retailers, the market price is exogenous, the retailers are symmetry and they sell the same perishable product, the market demand is stochastic. There (exist) inventory competition among them. When the supplier adopts buy back contract, the retail inventory game exists an (unique) pure-strategic Nash equilibrium. Buy back contract can coordinate the above supply chain and divide the whole (expected) profit between supplier and retailers arbitrarily. At last we discuss some reasons why Buy back contract is popular in practice.
